    Abstract: Adjuvant use of laser with systemic chemotherapy for treatment of retinoblastoma may reduce recurrence rates while also causing local side effects. Information is lacking on the effect of laser on visual outcomes. Methods A retrospective review of two retinoblastoma centres in the United Kingdom was conducted. Patients were included if there was a macular tumour in at least one eye. Eyes that received chemotherapy alone were compared with eyes that received chemotherapy plus adjuvant laser. Results A total of 76 patients and 91 eyes were included in the study. Systemic chemotherapy alone was used in 71 eyes while chemotherapy plus laser was used in 20 eyes. Demographic characteristics of both groups were similar. Macular relapse rates were similar between groups: 22/71 (31%) eyes in chemotherapy group and 9/20 (45%) eyes in laser group (p=0.29). There was no increase in vitreous relapses in the laser group (2/20 eyes), compared with the chemotherapy group 10/71 eyes (p=0.99). Survival analysis demonstrated similar time to first relapse between groups. Final visual acuity was equal between groups with 6/15 or better present in 31.1% of eyes in the chemotherapy group and 37.5% of eyes in the laser group (p=0.76). Presence of tumour at the fovea was predictive of final visual acuity, regardless of treatment group. Conclusion Adjuvant laser in the treatment of retinoblastoma is safe and does not lead to increased rate of vitreous recurrence. Final visual acuity is determined by the presence of tumour at the fovea and not the use of laser.

    Abstract: To investigate the outcomes of primary photodynamic therapy (PDT) for pigmented posterior pole cT1a choroidal melanoma. Methods Retrospective interventional consecutive case series of 26 patients (26 eyes) with pigmented posterior pole cT1a choroidal melanoma, who were treated with 3 sessions of PDT and followed-up thereafter. Results Included were 11 males and 15 females that presented at a median age of 66 years (mean: 64) with transformed naevi (n=11) or suspicious lesions (n=15) with ≥3 risk factors for growth, with lipofuscin in all. In all cases, diagnosis was clinically based (no tissue biopsy). Tumour control was achieved in 16 (62%) patients in a median follow-up time of 29 months (mean: 27). Ten patients failed treatment by form of radial expansion, diagnosed in a median time of 13 months (mean: 12) from last treatment. By Kaplan-Meier analysis, success rate after 1, 2 and 3 years was 85%, 59% and 51%, respectively. On statistical analysis, number of suspicious features was found to be the only risk factor predicting failure (P=0.046). One patient developed macula-sparing branch retinal artery occlusion after treatment. Following PDT, subretinal fluid resolved in all cases and visual acuity significantly improved in all treatment-success cases (P=0.043). There were no cases of metastatic spread. Conclusion Primary PDT resulted in tumour regression of small, pigmented choroidal melanoma in 62% after a mean of 27 months. Treatment was more effective in tumours with three or less risk factors for growth, and resulted with fluid elimination and significant improvement in vision in treatment-success cases.

    Abstract: The travel distance from home to a treatment centre, which may impact the stage at diagnosis, has not been investigated for retinoblastoma, the most common childhood eye cancer. We aimed to investigate the travel burden and its impact on clinical presentation in a large sample of patients with retinoblastoma from Africa and Europe. Methods A cross-sectional analysis including 518 treatment-naïve patients with retinoblastoma residing in 40 European countries and 1024 treatment-naïve patients with retinoblastoma residing in 43 African countries. Results Capture rate was 42.2% of expected patients from Africa and 108.8% from Europe. African patients were older (95% CI −12.4 to −5.4, p 〈 0.001), had fewer cases of familial retinoblastoma (95% CI 2.0 to 5.3, p 〈 0.001) and presented with more advanced disease (95% CI 6.0 to 9.8, p 〈 0.001); 43.4% and 15.4% of Africans had extraocular retinoblastoma and distant metastasis at the time of diagnosis, respectively, compared to 2.9% and 1.0% of the Europeans. To reach a retinoblastoma centre, European patients travelled 421.8 km compared to Africans who travelled 185.7 km (p 〈 0.001). On regression analysis, lower-national income level, African residence and older age (p 〈 0.001), but not travel distance (p=0.19), were risk factors for advanced disease. Conclusions Fewer than half the expected number of patients with retinoblastoma presented to African referral centres in 2017, suggesting poor awareness or other barriers to access. Despite the relatively shorter distance travelled by African patients, they presented with later-stage disease. Health education about retinoblastoma is needed for carers and health workers in Africa in order to increase capture rate and promote early referral.

    Abstract: Early diagnosis strategies and advances in retinoblastoma (Rb) management have resulted in nearly 100% survival. More attention should, therefore, be given to quality of life considerations. We aimed to quantify the number of examinations under anaesthesia (EUAs) in a cohort of patients with Rb, as a measure of disease burden. Methods A retrospective analysis of patients with unilateral Rb that presented to the London Rb service from 2006 to 2013, were treated and had long-term follow-up. Correlations of clinical variables to number of EUAs were investigated. Results A total of 107 patients with Rb were included that presented at a mean age of 26.51 ± 22.68 months. The International Intraocular Retinoblastoma Classification (IIRC) was group B in 5 (5%), C in 13 (12%), D in 48 (45%) and E in 41 (38%) of the cases. Primary treatment was intravenous chemotherapy in 36 (34%) and enucleation in 71 (66%) of the cases. Mean number of EUAs was 20.67 ± 6.62, 12.52 ± 6.23 and 11.15 ± 6.91 for combined groups B/C, group D and group E patients (p 〈 0.001), respectively. On analysis, early age atpresentation and conservative treatments were found to significantly correlate with increased number of EUAs (p 〈 0.001). Mean follow-up time was 74.42 ± 25.16 months and no metastasis or death were reported. Conclusion Families should be counselled regarding the number of EUAs associated with the patient's IIRC group, with B/C eyes undergoing twice the number as compared with D/E eyes. For group D cases, where both enucleation and conservative therapy are valid options, treatment choice has a significant impact on the number of EUAs.

    Abstract: Naevus of Ota is a congenital condition that may involve the skin, eyeball and even intracranial structures usually in the distribution of the ophthalmic and maxillary divisions of the trigeminal cranial nerve. The purpose of this study was to summarise our experience with the ocular clinical presentation, imaging, outcome, treatment of complications and to offer a new classification of patients with naevus of Ota. Methods We retrospectively reviewed the patients’ medical records and the following parameters were retrieved and analysed: demographics, clinical presentation complications and treatment of complications. Imaging characteristics of patients with naevus of Ota were compared with images from the same period of time of 57 age-matched and gender-matched patients without naevus of Ota (control group). Results The series was composed of 40 patients (18 males, 22 females) whose mean age at diagnosis was 35.27 years (range 0.5–77 years). Thirty-three patients (82.5%) were type I naevus of Ota according to the Tanino classification, three patients (7.5%) were type II, one patient (2.5%) was type III and three patient (7.5%) were type IV (bilateral naevus of Ota). We further classified all cases in according to the ocular involvement extent. Three patients developed malignant transformation to choroidal melanoma and four patients developed glaucoma. Conclusions In this study, a new clinical classification based on the involved ocular component and extent of the involvement (in quadrants) of the globe is suggested first. Further studies are needed to assess whether our clinical ocular classification can assist in identifying patients at risk for developing glaucoma and malignant transformation.

    Abstract: The relationship between the ethnic background or socioeconomic status (SES) and late retinoblastoma (Rb) presentation in the UK is unclear. We aimed to investigate if such correlations exist in a cohort of non-familial Rb cases. Methods A cross-sectional study based at the two centres providing Rb care in the UK. Included were non-familial Rb cases that presented from January 2006 to December 2011. Epidemiological and clinical data were retrieved from medical charts, as well as patients’ postcodes used to obtain the Index of Multiple Deprivation (IMD) score. A postal questionnaire was sent to participants’ parents to collect further, person-level, information on languages spoken and household socioeconomic position. Statistical correlations to advanced Rb at presentation as well as to treatment by enucleation and need for adjuvant chemotherapy were investigated. Results The cohort included 189 cases, 98 (51.8%) of which were males. The median age at diagnosis was 16 months (IQR 8–34 months). Of the study patients, 153 (81%) presented with advanced Rb; 78 (41%) with group D and 75 (40%) with group E Rb. A total of 134 (72%) patients were treated with enucleation. South Asian ethnicity and being in the most deprived IMD quintile were associated with a higher likelihood of presentation with advanced disease, but these estimates did not reach statistical significance. Older age at presentation was associated with enucleation and bilateral disease with adjuvant chemotherapy. Conclusions In this national UK study of patients with non-familial Rb, there was no evidence of an association of ethnicity or SES and the risk of presenting with advanced disease. These findings may reflect equality in access of healthcare in the UK.

    Abstract: Rates of care abandonment for retinoblastoma (RB) demonstrate significant geographical variation; however, other variables that place a patient at risk of abandoning care remain unclear. This study aims to identify the risk factors for care abandonment across a multinational set of patients. Methods A prospective, observational study of 692 patients from 11 RB centres in 10 countries was conducted from 1 January 2019 to 31 December 2019. Multivariate logistic regression was used to identify risk factors associated with higher rates of care abandonment. Results Logistic regression showed a higher risk of abandoning care based on country (high-risk countries include Bangladesh (OR=18.1), Pakistan (OR=45.5) and Peru (OR=9.23), p 〈 0.001), female sex (OR=2.39, p=0.013) and advanced clinical stage (OR=4.22, p 〈 0.001). Enucleation as primary treatment was not associated with a higher risk of care abandonment (OR=0.59, p=0.206). Conclusion Country, advanced disease and female sex were all associated with higher rates of abandonment. In this analysis, enucleation as the primary treatment was not associated with abandonment. Further research investigating cultural barriers can enable the building of targeted retention strategies unique to each country.
